Beyond the Flat-Band Paradigm: Open Orbits as a Route to Correlated States in Dispersive Moiré Minibands
Zihao Wang, Pablo M. Perez-Piskunow, Calvin Pei Yu Wong +16
The realization of fractional Chern insulators has largely relied on isolated flat bands in complex bilayer or multilayer moiré systems with ideal quantum geometry. Whether such ph…
Commensuration torques in double-moiré twisted trilayer hexagonal boron nitride and graphene heterostructures
Youngju Park, Nicolas Leconte, Prathap Kumar Jharapla +3
We study commensuration-driven torques and angle locking in double-moiré trilayer hexagonal boron nitride (hBN) and graphene heterostructures using large-scale atomistic relaxation…
Supermoiré domain-resolved effective Hamiltonians and valley topology in helical multilayer graphene
Kyungjin Shin, Nicolas Leconte, Jeil Jung +1
Extending moiré graphene beyond twisted bilayers, helical trilayer graphene has shown topological bands and correlated states with reshaped moiré periodicity. Here we develop a the…
Atomistic substrate relaxation effects in the band gaps of graphene on hexagonal boron nitride
Jiaqi An, Nicolas Leconte, Srivani Javvaji +2
We assess the impact of atomistic substrate lattice relaxation schemes in the primary band gap at charge neutrality and the secondary valence band gap of graphene on hexagonal boro…
Geometric control of the moire twist angle in heterobilayer flakes
Prathap Kumar Jharapla, Nicolas Leconte, Zhiren He +2
We demonstrate a finite twist-angle stabilization mechanism in lattice-mismatched 2D heterobilayers, which results from the geometric alignment between the flake edges and its moir…

Dohun Kim, Gyeoul Lee, Nicolas Leconte +6
Trilayer graphene allows systematic control of its electronic structure through stacking sequence and twist geometry, providing a versatile platform for correlated states. Here we…
Optical control of the moiré twist angle
Zhiren He, Prathap Kumar Jharapla, Nicolas Leconte +2
In this theoretical work, we propose an all-optical method for fast, precise manipulation of two-dimensional multilayers by transferring orbital angular momentum from phase-structu…
Moiré flat bands and antiferroelectric domains in lattice relaxed twisted bilayer hexagonal boron nitride under perpendicular electric fields
Fengping Li, Dongkyu Lee, Nicolas Leconte +2
Local interlayer charge polarization of twisted bilayer hexagonal boron nitride (t2BN) is calculated and parametrized as a function of twist angle and perpendicular electric fields…
Observation of dichotomic field-tunable electronic structure in twisted monolayer-bilayer graphene
Hongyun Zhang, Qian Li, Youngju Park +18
Twisted bilayer graphene (tBLG) provides a fascinating platform for engineering flat bands and inducing correlated phenomena. By designing the stacking architecture of graphene lay…
